I think it also depends a lot on where you are. Being a NYC based company (and that NYC is a high population density city) I've found it useful here (both with people I actually know on it as well as a quick way to look up tips about places nearby). That being said, when I've been in other cities that aren't NYC/SF the value drops quite a bit (I don't have friends in those cities that use it and the number/quality of tips on places isn't the same). The anti-social aspect is probably the biggest issue for really using it when you're out.
